LAMP-BURNER.

SPECIFICATION forming part of Letters Patent No. 603,116, dated April 26, 1898.

Application filed December 2l, 1897. Serial No. 662,956. (No model.) Fatented in England May 14,1897,No. 11,985; in France May 18,1897,N0. 267.028; in Belgium June 16, 1897,1Io. 128,910, and in Austria October 6, 1897, Noy 3,842.

To 5l/ZZ whom, it runny concern:

Be it known that I, .I AMES H. OBRIEN, of the city of St. Louis, State of Missouri, have invented certain new and useful Improvements in Lamp-Burners, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming a part hereof.

rlhis invention has been patented to me in the following foreign countries: Great Britain May lll, 1397, No. 11,985; France May 18, 1897, No. 267,028; Belgium June 16, 1897, No. 128,910, and Austria October G, 1897,No. 3,842.

My invention relates to lamp-burners; and it consists in a novel construction, combination, and arrangement of the parts hereinafter shown, described, and claimed.

The object of my invention is to provide improved means whereby the upper corners of an ordinary lamp-wick may be raised or lowered independently of each other, as required to cause the flame of the lamp to burn evenly, even though the wick be not evenly trimmed.

Figure 1 is a transverse vertical sectional view taken through the center of a burner constructed in accordance with my invention. Fig. 2 is a horizontal sectional view taken approximately on the indicated line 2 2 of Fig. 1. Fig. 3 is a view in perspective of the wicktube of my improved burner before said wicktube has been positioned in said burner. Fig. l1 is a view in perspective of the wick-tube as it appears after being positioned in the burner. Fig. 5 is a transverse sectional view taken approximately on the indicated line 5 5 of Fig. 3. Fig. 6 is an enlarged vertical sectional view taken approximately on the indicated line 6 6 of Fig. 2.

In the construction of my improved burner the wick-tube 1 is a suitable length of dattened pipe, the same being vertically positioned inthe lamp-burner in the usual manner. Formed in the lower portion of each side of the wick-tube is an aperture 2, which apertures are rectangular in form'and located slightly above the lower edge of the wick-tube and at points slightly to one side of the center of said tube. Extending downwardly from the side edges of each of these apertures 2 are the slits 3 and e, which slits 3 extend entirely to the lower edge of the wick-tube, while the slits 4 stop a short distance from the lower edge. During the construction of these tubes the rectangular sections 5 between slits 3 and 4 and below the apertures 2 have their centers bent inwardly, and said sections are bent at right angles into the wick-tube. The positions these sections 5 assume after being so bent are clearly illustrated in Figs. 3 and 5. The pair of shafts (i are mounted for rotation in the lower portion of the burner, and toothed wheels 7, such as are usually employed in lamp-burners, are iixed upon said shafts. Upon the outer end of each of the shafts 6` is iixed a finger-wheel S. After the burners have been provided with these shafts and toothed wheels the wick-tube 1 is passed downwardly into said burner, during which movement the toothed wheels 7 will pass into the apertures 2 in said tube, and when so positioned said tube is .soldered or iixed in any suitable manner. The sections 5 are now bent outwardly from the interior of the wicktube or in such a position as that the lower ends of said sections coincide with the sides of the wick-tube. The ordinary wick is now passedinto the lower end of the wick-tube and upwardly therein until it can be engaged by the toothed wheels 7, and as said wick moves vertically in said tube the sections 5 yieldingly engage the faces of said wick, and said sections may therefore be termed frictiontongues. The toothed wheels 7 engage the wick on opposite sides and near the opposite edges, and bymanip ulatin g one of said wheels 7 the corresponding upper corner of the wick may be raised or lowered independently of the other corner, and by manipulating both of said wheels simultaneously all parts of the wick maybe simultaneouslyraised or lowered. Each of the wheels 7, together with its correspondingfriction-tongue, coacts to hold either side of the wick from vertical movement during the manipulation of the opposite toothed wheel.

A lamp-burner of my improved construction is simple, inexpensive, easily constructed, and a very accurate adjustment for the wick is obtained, and the llame from said wick can always be made to burn very evenly, even though said wick be unevenly trimmed.

ICO

I claim- In a lamp-burner, a pair of shafts mounted in horizontal parallel positions, a wick-tube mounted between said shafts, a toothed wheel upon one of said shafts and extending through a slot in one wall of said wick-tube near one of its edges and to the opposite Wall of the wick-tube, a second toothed wheel upon the other one of said shafts extending through a slot in the opposite wall of the Wick-tube near the opposite one of its edges and to the rstmentioned wall, said slots having each a long vertical slit 3 extending to the lower end of said wick-tube, and a shorter slit 4 extending to a point adjacent said lower end, whereby the metal 5 between said slits may be bent inwardly and permit the end of the said tube to be slipped over the said toothed wheels and then said metal may be bent outwardly again after the tube has been placed in position, and finger-wheels upon said shafts and upon opposite sides of the burner as required to raise and lower the corners of the wick independently of each other and as required to raise or lower the entire wick by manually grasping one nger-wheel in each hand and exerting a twisting motion of the hands relative to each other, substantially as speeied. In testimony whereof I affix my signature in presence of two witnesses.
